Be it known that I, CHARLES a citizen'of tlie'United States, residing New York city and State of Nlew York, have invented certain new and 'useful Improvements in Pneumatic-Despatch Carriers, of which the followthereof; but a ing is a specific tion.

This invention relates to carriers for pneumatic-despatching-tube'systems, and has in/ view certain practical and effective improvements in carriers of this character whereby the same shall be rendered perfectly safe and secure against damage o r escape ofthe carrier contents.

. To this end the invention contemplates an improved door equipment and fastening for a pneumatic-despatch carrier wherein thedoor or cover 1s -capable of completeand ready removal, while-at the same time being so securely fastened or locked when. in place as to be entirely secure against accidental displacement or unlocking during transit.

'With these and other objects in view, which willreadily appear to those familiar with the art as the nature of the invention is better understood, the saine consists in the novel construction, combination, and arrangementof parts hereinafter more fully described, illustrated, and claimed.

'T he essential features of the invention are necessarily susceptible to structural modifications without departing from the scope preferred embodiment of the invention 1s shown in the accompanying drawings, in 'which- Figure 1 isa side elevation or plan view of a pneumatic-desp atch carrier 'embodying the present invention. Fig. 2 is an end view of the carrier. Fig. 3 is a cross-sectional view on the line 3 3 ofFigi. Fig. 4 is a sectional view on the line 4 4 of Fig. 1, showing the sliding securing-bolt in its lockedjposition Fig. 5 is a similar view showing the sliding securing-bolt in its unlocked position. Fig. 6 is a ployed for unlocking the device.

Like references designate corresponding parts in the several figures of the drawings. In carrying out the invention no special change is required in the conventional or practical features of any carrier for a tem, so for approved type of pneumatic-despatch-tube sys- 1 lustrative purposes there is -etail view of the tool orI wrench em rprojected from the inner slots 16, provided in the bar 9.

shown in the drawings an ordinary form of body portion l, having `n`1 the county of New York il the usual head ends Zand carrying-upon said vided therein with an access-opening 4 of any suitable dimensions and through which the contents of the carrier are introduced and removed. lThis opening is designed to be covered and uncovered by a removable door or cover 5, adapted to be seated flush or `substantially iiush within said opening and carryingat one side or one side edge a plurality of hasp-bars .6. These bars are riveted or otherwise permanently fastened to the door and are formed with deflected engaging'end portions 7, projecting beyond one edge of the door and adapted to be inserted through keeper-openings 8, provided therefor in the carrier-body near one edge of the opening 4. Hence the projecting ends 7 of the hasp-bars 6 engage inside of the carrier-body, and upon the side edgeportion of the door or cover opposite the hasp-bars is arranged a swinging fastener-bar 9.

The fastener-bar 9 is formed with a plurali'ty ofA bolting-arms l10, projecting from one side thereof in regular spaced relation and adapted to extend through keeper-openings 11, provided in the door 5 nea'r one edge thereof, the extremities of the arms 10 beyond the bar 9 being also adapted to extend beneath or vbehind one edge portion or the opening 4, so that the arms 10 will act as swing-bolts for one side of the door. The lthe arms 1() within the openings 11 are pivotally connected t0 door 5 at 11a. The fastener-bar 9 has arranged at its inner side in parallelism thereto what may be termed afsliding securing-bolt 12, having side thereof a plu'- ralityof spaced locking-hooks 13, adapted to'project through catch-openings 14 in the body of the door 5 and engage behind the latter at one edge of such opening.

The sliding bolt 12 has a sliding coupled connection with the bar 9. This is preferably eifected by the employment of a series of headed coupling-studs 15, secured to the .bolt 12 and projecting through the play- Also the latter has attached thereto a spring-latch 16a,

lIOO

`'carrying at its'free -end portion a beveledr lock-pin 1 7, adapted to project through registering openings 18 in the barv 9 Iand bolt 12,

thus providing for locking seid two elements against relative movement when the hooks 13 of .the bolt 12 are 'engaged .in the openings 14. I/Vhen the spring-latch 16 is lifted out of engagement with the openings v18, the

bolt 12 may be slid to en unlocked position, so that the hooks 13 may be lifted out-of the openings. 14 through "the employment of en operating too-l orwrench 19. v This tool 'or Wrench carries spaced. leverage-pins 20, adapted to be`respectively inserted in` e i'iilcrurn-opening 21 in one of the. boltingf'airni's 1() ande tool-bearing socket 22,-,ior1ne'd inl theadjacent one of the coupling-studs 1'5;`

When the bolt 1`2is slid back to the unlocked position referred to, the hooks 13min be lifted out otheir openings 14 vand thebolting-'arms' 310 swung inwardfto a position from behjndthe edgef the openingggi, thus permitting the doei` to be swung' open; and
